FIRE-ESCAPE.

SPECIFICATION forming part of Letters Patent No. 299,967, dated June 10,1884. Application filcd August 14, 1883. (X0 model.)

To all whom it may concern Be it known that I, OSCAR F. DAVIS, a citizenof the United States, residing at the city of Topeka, in the county ofShawnee and State of Kansas, have invented a new and useful Improvementin Fire-Escapes, of which the following is a specification.

The objects of my invention are to overcome the practical difficultywhich arises in the manipulation of the brake orlock of my improvedfire-escape for which Letters Patent of the United States were allowedme June 7, 1882, Serial No. 50,216, when the said escape is reversed inuse and the said brake is necessarily operated at the upper part of theescape to insure promptness in arranging the escape for successivedescents, and to protect the person descending from striking against theground.

' I attain these objects by the mechanism illusfriction (more or less)by being forced by means of the brake N G and its lever D against theopposite friction-shoulders P and P.

The brake N G is readily operated in using the escape when the loose endof the lever D points downward toward the person manipulating it; but itis operated with more or less difficulty by different persons when theescape is reversed, and this same loose end of the lever points upward,and is necessarily manipulated from the upper part of the escape. Iovercome this difficulty by the additional combination of the brake G N,lever D, and friction-shoulders P and P", whereby a brake and lever aresimilarly presented to the operator from either end of the escape.Again, with a loop and knot, A, provided at each end of the rope A, whenin place in the escape, the escape cannot be drawn off of the rope, andeither end of the rope may promptly and indifferently be secured to itsfastening within the room, and the length of the rope being properlydetermined, theperson descending is kept from striking upon the ground,and may be stopped and taken from the escape at any point above theground.

What I claim as novel in the device now described, and desire to secureby Letters Patent, is

1. The combination of the friction-boX O, with-its studs L and its twobrakes, N G and N G, and levers D and D at each end and upon theopposite edges of the friction-box, all constructed and operating as andfor the purpose hereinbefore set forth.

2. Thecombination of the friction-box G, constructed as hereinbeforedescribed, having a friction device upon both ends and sides, with arope, A, having a loop and knot, A, at each end, operating asand for thepurpose hereinbefore set forth.
